polymer
chain of monomers (subunits of polymer molecules)

New cards
monomers
a molecule that can be bonded to other identical molecules to form a polymer.
4
New cards
metabolism
the combination of chemical reactions through which an organism builds up or breaks down materials
5
New cards
catabolism
a form of metabolism using energy to break down molecules (eg. starch is broken down into amylose and amylopectin)
6
New cards
anabolism
a form of metabolism that requiring energy to form larger molecules (glycerol and fatty acids make up triglyceride molecules)
7
New cards
enzymes
Catalysts for chemical reactions in living things, help break down and speed up chemical reactions
8
New cards
dehydration synthesis
condensation reaction where molecules are connected by loss of a water molecule.
9
New cards
hydrolysis
breaking down complex molecules by the chemical addition of water
